Talk to Endocrinologist on Thyroid/ PCOS

I am a 25-year-old girl and I have been experiencing several symptoms for some time:

• Hair thinning and increased hair fall • Facial puffiness/bloating • Weight gain, especially around my abdomen • Excess fat around my neck/double chin • Late/irregular menstrual cycles • Weak eyesight

People have suggested that these symptoms could be related to a thyroid problem, but I am not sure.

Could a doctor please guide me about:

1. Whether these symptoms could indicate hypothyroidism, hyperthyroidism, or another hormonal problem? 2. Which blood tests should I get done before my appointment to check my thyroid? 3. Should I also be tested for other hormonal conditions such as PCOS, insulin resistance, or vitamin deficiencies?

I would like to get the appropriate tests done and then consult an endocrinologist with the reports. Thank you.
